This implements customizable initramfs compression, based on the Pentoo
genkernel fork (SVN revs r2142, r2145, by Jens Pranaitis
<jens@chaox.net>).
New configuration option COMPRESS_INITRD_TYPE to allow manual selection,
whereas the Pentoo fork provided auto-selection based on what was
available in the kernel configuration. Auto-selection is used by
default, and is available with the argument of 'best' to the new option.

The existing multipath functionality manually picks up a binary and lots
of needed libraries manually, and sometimes misses libraries if the
binary was linked against something else.
Use lddtree from app-misc/pax-utils to get all libraries with the
binary. The only ones that will be missed are those that are dlopen()ed.
cpio is used for copying to preserve directory structure.
lddtree usage replaces a larger manual function from calling ldd, that
was also vulnerable to injections.

When using an integrated initramfs (including in kernel during build),
it's better NOT to compress the initramfs, as the kernel build process
will then be re-compressing it. This can provide space savings on disk
as well as potential time & memory savings (one less decompress pass is
needed before the kernel can use the initramfs).
This functionality was previously available in the undocumented
COMPRESS_INITRD variable.

Hello,
Due to the changes in glibc-2.14 busybox no longer compiles when NFS
support is enabled. This breaks genkernel. The following is a very
crude patch to just make things work on glibc-2.14 systems. A better
patch would be to detect glibc-2.14 and then make a config decision.
The best patch would be to port libtirpc to openssl, make busybox link
against libtirpc, restore NFS support, and put an end to this whole
mess. But in the meantime:

Disable NFS support to enable glibc-2.14 compatibility
Provide real boolean commandline options for options that were
previously only available as booleans in the config, so that they can be
enable in configuration and overridden to disable on the commandline.
Remove negation on options: NOINSTALL, NORAMDISKMODULES,
NO_KERNEL_SOURCES.
